+# Steam Guard Support Explained
+
+## What is Steam Guard?
+Steam Guard is Valve's two-factor authentication (2FA) system that protects Steam accounts from unauthorized access. When logging in from a new device or after clearing credentials, Steam requires a verification code.
+
+## How the Script Handles Steam Guard
+
+### Current Implementation
+The script **does not automatically handle** Steam Guard codes. Instead, it:
+
+1. **Opens SteamCMD in its own console window** when you click "Update Server"
+2. **You interact directly with SteamCMD** to enter any required codes
+3. **SteamCMD handles the authentication** normally, just like running it manually
+
+### What You'll See
+When logging in with Steam Guard enabled, SteamCMD will display:
+
+This account is protected by a Steam Guard mobile authenticator.
+Please confirm the login in the Steam Mobile app on your phone.
+
+OR -
+Please enter the authentication code from your email:
+
+
+### What You Need To Do
+1. **Mobile Authenticator**: Approve the login in the Steam Mobile App
+2. **Email Codes**: Type the code sent to your email directly into the SteamCMD window
+3. **The code entry happens in the SteamCMD console window**, not the GUI
+
+### Why No Automatic Popup?
+- SteamCMD manages its own authentication flow
+- Creating a popup would overcomplicate the process
+- Manual entry is more reliable and secure
+- Your password is never stored (for security)
+
+## Workflow Example
+
+1. You check "Use Steam Login"
+
+2. Enter username and password
+
+3. Click "Update Server"
+
+4. SteamCMD window opens
+
+5. SteamCMD says "Please enter authentication code"
+
+6. You type the code from your email/app
+
+7. Login completes, server downloads
+
+
+## Steam Guard Options
+
+| Type | How it works in script |
+|------|----------------------|
+| **Mobile Authenticator** | Approve on phone, SteamCMD proceeds automatically |
+| **Email Codes** | Type the 5-digit code into SteamCMD window |
+| **Steam Guard Disabled** | No extra steps, logs in directly |
+
+## Security Notes
+- ✅ Passwords are **NOT saved** to the config file
+- ✅ Username is saved for convenience
+- ✅ Steam Guard codes are never seen or stored by the script
+- ✅ You type codes directly into SteamCMD, not the GUI
+
+## Troubleshooting Steam Guard
+
+**Problem**: "Waiting for confirmation... OK" but nothing happens
+- **Solution**: Check your Steam Mobile App - you may need to approve there
+
+**Problem**: "Please enter authentication code" but no code arrives
+- **Solution**: Check spam folder, or use mobile authenticator instead
+
+**Problem**: Login times out repeatedly
+- **Solution**: Close SteamCMD, wait 30 seconds, try again
+
+## Example SteamCMD Output with Steam Guard
+
+Logging in using username/password.
+Logging in user 'username' [U:1:12345678] to Steam Public...
+This account is protected by a Steam Guard mobile authenticator.
+Please confirm the login in the Steam Mobile app on your phone.
+
+Waiting for confirmation...OK
+Waiting for client config...OK
+Waiting for user info...OK
+
+
+## Recommended Setup
+For the smoothest experience with the script:
+1. **Use Steam Mobile Authenticator** (approve with one tap)
+2. **Stay logged into the Steam client** on your PC
+3. **Check "Remember me"** when logging in via SteamCMD (it caches your login)
+
+## Note
+The script cannot bypass Steam Guard - this is intentional for account security. You must have access to your email or mobile device to authenticate.
